History of discovery of Electricity

Benjamin Franklin is known as the first person who discovered electricity. Benjamin was born in 1705, he began studying electricity at the beginning of the year 1750an. He was doing research one with kite experiment to prove the existence of a natural power. In 1752 he did experiment by placing a sharp metal tip on the end of a kite string locks fitted.

Benjamin first who discovered the principles of electricity and also give positive and negative electricity. He then published his experiments to prove that lightning is actually electricity by flying a kite in a storm. In his writings, Benjamin Franklin wrote that he was aware of the dangers that can result from the experiments and offer an alternative that proves that lightning is electricity, which is then in the show by using the concept of electrical ground. Not as pictured person that Benjamin experiment done by flying a kite and wait until the kite was struck by lightning. Benjamin uses his kite just to collect electricity from storm clouds.
Experiments to electricity by Benjamin, directing him to the invention, the lightning rod. He wrote that the conductor (electric) with a sharp edge has the ability to draw an electrical charge and has a range of further withdrawals than conductors with a blunt tip. He concluded that this knowledge can be used to protect the house from lightning danger, by putting an iron bar seruncing pointy needles and anti-rust coating, which is directed to the sky, and the legs of iron, attached with wires leading to the ground. This will attract the lightning rod at electric charge cloud to the ground so that the charge is on the cloud is not enough to cause thunder and lightning.
During the years 1750-1850 are found important discoveries about the working principle of such power by Volta, Couloumb, Gauss, Henry, and Faraday.
